Definitions
- the invention relates to a fabric which is formed at least in two layers at least in a section of at least one of its two selvedges
- Fabrics consist of warp threads and weft threads, which are woven between the warp threads, whereby different weaves are distinguished depending on the type of weaving.
- the edges that run along the warp thread are called selvedges
- a two-ply fabric web for the production of airbags is known from US 1,991,249 A. It is important that the individual airbags woven one behind the other in the direction of the warp threads can be separated from one another without the cohesion of the fabric layers combined there being lost. To achieve this goal To achieve this, complex weaving processes are carried out, through which an intermediate strip is formed, in the area of which the fabric web is separated.
- Fabric webs are now frequently produced, in which a plurality of fabric strips are produced side by side, which are cut between predetermined warp threads after the fabric web has been produced, or become independent of one another in some other way.
- a plurality of fabric strips are produced side by side, which are cut between predetermined warp threads after the fabric web has been produced, or become independent of one another in some other way.
- it has already become known not to tension a few warp threads at the appropriate points, but at this point to provide appropriate edging devices.
- these cut the weft at the predetermined location between the adjacent fabric sheets and knock each of the excesses of the weft into the next compartment. In this way it is possible to obtain clean selvedges of each of the fabric strips next to one another even when producing a plurality of fabric strips
- fabric webs are produced which, at least in sections, consist of two or more layers along at least one of their two selvedges.
- An example of this is described in EP 0 640 155 A.
- the fabric web disclosed there is a woven sack in which the warp threads run in the direction of the sack bottom or the upper sack edge, these upper edges remaining continuous in two layers, from Filling machines can be handled
- the invention also relates to a method for producing such fabrics.
- This method according to the invention consists in opening at least the warp threads which are in the area of the excess of the weft thread to be opened into a new compartment when weaving a fabric of the type defined at the outset after the last weft of a layer has been fired, the excess of the last weft thread of this layer to fold over to a folding edge and shoot an empty ship and then open the warp thread to the first compartment of the next layer and shoot the first weft thread of this layer
- the single figure shows a section of a fabric web 1, which has a single-layer area 2 and a two-day area 3.
- the fabric web 1 consists of weft thread Si and warp thread Ki, the index "i" each indicating the sequential sequence of the threads
- the warp thread Kl is the outermost warp thread (selvedge) of the single-layer region 2 and the upper layer of the two-layer region 3
- the warp thread K2 is the outermost warp thread (selvedge) of the lower layer of the two-layer region 3.
- the weft SI is the first weft to be shot. After shooting, it is cut off with a protrusion UI, then (or simultaneously) the next compartment for the weft S2 is opened. Before the weft thread S2 is fired, the excess UI is folded over into the compartment which has just been opened and then the weft thread S2 is fired.
- the weft thread S4 is the last weft thread lying in the single-layer area 2. Its protrusion U4 is not moved into the compartment of the next weft thread S5, but a separate compartment is opened, as can be seen in the figure, which Overhang U4 is flipped over and an empty ship is shot, then the compartment for S5 is opened and S5 is shot. The overhang U5 from S5 is again placed in the compartment of S6 in a conventional manner, which is not a problem because of the identical warp threads involved
- the last weft S8 of the upper fabric layer has a protrusion U8. It can be seen directly from the figure that U8 cannot be placed in the compartment of the subsequent weft S9 without being destroyed.
- a new compartment is opened after S8 has been fired (in the position of S8, the upper one) opened, S8 is flipped over and an empty ship is shot, then the compartment for S9, the first weft thread of the lower layer is opened and S9 is shot.
- the invention is of course not limited to the described embodiment or even to the illustrated embodiment. According to the invention, more than two-layer fabrics (areas) and other sequences of the wefts are to be treated as well as the variant shown.
- the type of binding is irrelevant to the invention; the invention is applicable to all types of binding.
